4850 or 5770

hello
I have: asus m2n-e - amd athlonx2 4800+ - 2*1gb 800mhz kingston hyperx
my psu is a green 430a with 430w power and on 12v rail can give maximum 300w and 30a
my higest res will be 1024*1280 .In 2 years I cant upgrade all of it
And theretofore I wanna play games in high detail (of course 1024*1280)
with my psu what is your offer to me? I am thinking between 4850 and 5770
your idea?(anything)

You need a better PSU and CPU, the 4850 could be good for now, or a GTX260, use less power that ATI.

5770 is on the level of a 4870. 5750 is on the level of a 4850.

Your PSU can run both. 5770 is dx11 supported, so get what you can afford.

I'd go with the 5770 for the simple fact that its the new gen and has all the DX11 goodness, has several outputs, consumes less power, and runs with a 4870.

my cpu is low. do you think the card work good in my system?

^ Negative, the 5770 uses less power than the GTX260

Reply to jay2tall

Who know 5770's exactly power and amperage(on 12v)?

Reply to grishnukh

Don't know about it's amp requirement, but guru3d did their review on an i7 overclocked to 4GHz and a 5770. System peaked at 100% stress with 321 watts. At idle is was 221. Your system would run it at nearly it's max load, which is a huge no no for power supplies. You'd be better off upgrading that first.

they told us 5770 requires 321w& 40 amp! but this is the only review with this huge numbers! what u thinking and know about 5770's power and amp requirement
please!!!!!!!

5770 Specs:
Maximum board power: 108 Watts
Idle board power: 18 Watts
450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended

Well, if you're speaking of the card's requirement only, then jay2tall posted that. But this review measures the entire system, not just the card. You can't forget about everything else you have as well.

^ Yeah my post was card only. What brand is your 430w? I have a feeling it will run everything fine. 30A should be enough to drive that thing as long as you don't a ton of HD's and Optical drive and a dozen fans.

Reply to jay2tall

no!!!!!!
the brand is: Green:
http://www.green-case.com/products [...] del=GP430A
all i have in 12v rail is 350w and 30 amp maximum . other80w is on other voltages.
if that is true(requirement of 40 amp) so I lost anyway! and maybe I should think about 4770. but I am not sure it can handle all games specially like crysis in 1024*1280(gamer setting of course) I am sick of this issue!!

That 450W requirement is the total system wattage for a complete system. And there is NO way a 5770 requires 40A, that would be ridiculous. The 5870 requirement is 40A, I KNOW, I have the box at home dude.

Anandtech did their test and a 5770 on an i7 @3.33GHz consumed 256Watts on load. Well under your 430W.

Still, only 300w goes to the 12v rails. I wouldnt risk running a PSU at a high load like that, it just seems dangerous and unsafe to me.

But you're definitely right about the 40A requirement. Thats an seems like an overcompensation if you're running like 4 or 5 HDDs or something.

Reply to Xelios

of course total system is what I am talking about.if my total pc with 5770 reqires 40 amp on 12v what am i supposed to do? all i have is 30a

I would recommend the 5750 for your system for several reason I will list here:

1. Your processor is weak: athlonx2 4800+, has barely any cache and it's architecture is comparable to it's singe core counter part. You would bottleneck a GTX 260, however an HD 5750 should be fine (may be bottlenecked very little if anything).

2. Your PSU would bearly fit the power consumption of a HD 5750. You may need to disconnect any usb devices not needed. Your PSU will take some serious damage after extended length use, I would recommend switching it after 3 months~.

3. Cheaper than a GTX 260, it has DX 11 support/eyefinity. Here's a video of 3 monitors (I think they're 19"~ each, running WoW.
http://www.youtube.com/watch?v=1xqR8haPuUo

4. Lower heat than a HD 4850 or GTX 260.

5. Your PSU could NOT handle a GTX 260 for sure. An HD 4850 would completely decimate your PSU in a couple months.

6. I have an HD 4850, (XFX 1gb version) it rocks but it's missing Eyefinity/Dx11 which is a complete killer for me (I plan on having 4 monitors for complete geek immersion). Im picking up a HD 5770 or HD 5850 soon however to remedy the situation.

Total PSU power is 430w its fine, the requirement isn't 450w on the 12v rail.

Someone show me this 40A requirement, I am sure that is wrong. There is no way my 5870 has a 40A requirement, an so does a 5770. NO WAY.

What brand of PSU do you have.

It's fine.... but then again you don't have to believe me.

Someone tell mle a 430w PSU isn't enough? at 285w the PSU is at 66% utilization.

Thnx All But my basic problem is: always I can't choose !!!

Reply to grishnukh

^The 5770 costs more than the 4850, but out performs it and uses less power. Id go for the 5770 unless you are strapped for cash.

Reply to jay2tall

4770,5770,5750 all decent choices. 5770 being the strongest. Frankly DX11 is only a selling point if you have vista or win 7 or will be getting it adn my guess is you're on xp. I'd just do what ever is cheapest mostly the rest of your system will be holding back a mid range card in the 100-160 range now. the 5770 and 5750 have promise of a little more power then it currently does because the drivers are still fairly new.

Save money get a 4770 use that money you saved to upgrade the rest of your system in a few more months. and repeat!

Reply to IzzyCraft

At that resolution you really don't need a good card. The highest you should be looking at is the HD4770. It's also low power(barely need a power connector) and should be great for that resolution. Anything more powerful will just be a waste of money until you upgrade your CPU and/or monitor.

personaly I agree with you about price and my CPU but in most benchmarks i can see 4770 in 1024*1280 (crysis) with highest setting and AA cant handle the game perfectly and It's min fps is 18-20 so what you think?

GPUs shouldnt be chosen through resolution. Your need to look at several factors:

* Performance
* Power use
* Playable Resolution

Like you noticed 4770 cannot handle Crysis with AA, and you can expect low FPS during intense fighting.
The 5750 is the best choice for you since it will provide you with the same performance as an HD 4850 and give you the benefits of next generation cards without being too bottlenecked by your setup.
Yes it is more expensive than a 4850, but totally worth it.

You can go for a 4770 however you will sacrifice AA in most games, not to mention many other features like in depth distance (viewing objects far away) etc. The HD 4850 struggles with Crysis but gives barely-playable FPS with x8 AA/16 AF at resolutions 1600x1073~ (1280x1024 would be a breeze). The 5750 should add to this performance slightly, and give u the option to use 2 monitors with minimum fps drop.

4770 is too weak to play next generation games with all the eye candy.
anything above a HD 4850 or HD 5750 will be bottlenecked by your CPU.

Reply to AsAnAtheist

The HD4770 is only slightly less powerful than an HD4850. Compared to an HD5750 it probably lags behind in performance %20-30. Considering the card is currently about $50 more expensive than the HD4770 and will require a new PSU while an HD4770 wouldn't we are talking about over twice the price for a %20-30 increase in performance. Maybe you consider that "totally worth it" but I sure don't and I doubt many other people would either.
As for the crysis benchmarks whatever. If you want to spend over twice the money to max out the settings in one game then be my guest but at that resolution an HD4770 would be great for every other game. AsAnAtheist is entirely wrong about an HD4770 not being able to handle AA or "depth distance" at 1280x1024. The only scenario that will give that card any problems at that resolution is a maxed out Crysis. Crysis was released two years ago now and there's still no game that's more demanding and there aren't reports of any game that will top in the foreseeable future. The game is also quite cpu intensive so I'm not certain if the HD4770 would be the limiting factor in that situation in any case.

Thank all.
but guru3d is saying 5750 like 5770 in load + PC requires 40 amp on rail12v
do you think that is true? how can it be?
if yes, I don't have it! I have just 30

When I bought my GTX260, I ran all the system with a 500W PSU, and the GPU manufacturer said that I needed a 550W PSU at least.

Thanx for this bench
But What I got is the amperage problem because of this:
The power usage of a VGA card or a CPU is shared between the on the this rails:12v, 5v, 3.3v and VGA card's core uses 12v and it's memory uses 3.3v . there is somethings that I don't know and because of all this factors 5770 or 5750 Suddenly needs more current on rail 12v ( I don't know how much exactly) and possibly My PC with a 5770 or even 5750 needs more than 30amps.(of course I am not sure about it)
Who can exactly explain the detali about this issue?
